Floribunda rose plant named ‘JACideso’

ABSTRACT

Floribunda rose plant having fragrant lavender flowers in large rounded clusters and dark, glossy green foliage having good resistance to mildew and rust.

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety JACship (U.S. Plant Pat. No. 7,948) with the variety AROsedi (U.S. Plant Pat. No. 9,172).

The primary objective of this breeding was to produce a new rose variety having the rounded, vigorous, plant habit and large flower clusters of the female parent combined with the lavender flower color; deep green foliage; and fragrance of the male parent.

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Strong fragrance;

2. Lavender flower color;

3. Large rounded clusters;

4. Dark, glossy green foliage; and

5. Good disease resistance

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart (1966), except where ordinary dictionary significance of color is indicated.

Parentage:

Seed parent.—JACship (U.S. Plant Pat. No. 7,948).

When half blown, the upper sides of the petals are Red-Purple Group 64C; and the lower sides of the petals are Red-Purple Group 64D.

Sepals.—Color: Green Group 138B, often with Red-Purple Group 187C in areas exposed to bright sunlight. Surface texture: Covered in fine hairs. Length: ¾ inch. Width: ⅝ inch. There are three lightly appendaged sepals. There are two unappendaged sepals with hairy edges.

Receptacle.—Color: Green Group 138B. Shape: Funnel. Size: Medium (about {fraction (5/16)} inch×¼ inch). Surface: Smooth.

Peduncle.—Length: Medium (about 2 inches to 2½ inches). Surface: Glandular. Color: Green Group 138B, but where exposed to sunlight it is Greyed-Purple Group 183B. Strength: Stiff; erect.

Bloom:

Size.—Medium. Average open size is 3½ to 4 inches.

Borne.—Several together in rounded clusters of 3 to 7 blooms.

Stems.—Strength: Strong. Average length is about 14 to 18 inches.

Petalage.—Number of petals under normal conditions: 30.

Color.—The upper sides of the petals are Red-Purple Group 64C. The reverse sides of the petals are Red-Purple Group 64D. The base of each petal has a ¼ inch×⅜ inch Yellow 11D color spot. The major color on the upper side is Red-Purple Group 64C.

Variegations.—There are Green-White Group 157D streaks along the midrib of some of the guard petals.

Discoloration.—The general tonality at the end of the first day: No change. At the end of the third day: No change. No change through day five when the plant color will fade to Red-Purple Group 64D. Petal drop occurs by day six.

Fragrance.—Strong; spicy.

Petals:

Texture.—Thick; leathery.

Shape.—Round to slighty deltoid.

Base.—Rounded.

Apex.—Obtuse.

Form.—Tips slightly recurved.

Persistance.—Petals drop off cleanly before drying.

Lastingness.—On the plant: Fair (about 5-6 days). As a cut flower: Fair (about 6 days).
